Well, I broke down and bought the MAXX last night. I decided to try and kill the battery so to speak. This is off my first full charge with 4G the entire time. Obviously, I'm not gonna make judgements from one charge, but after the first day I'm impressed. I'm sure it'll only get better after a few charges. I was off last night, so this is more usage than normal. I'd consider this fairly heavy use (setting up the phone and downloading all apps, some calls and texting, playing a game, streaming netflix and youtube a bit). At the 15% battery warning, I was at a display time of 3h 42m and 43m of calls. I tried to make this detailed and post screenshots for the people that like them. I know I do. If anyone wants more updates or screenshots from the next couple of days, I'd be more than happy to post.
